unless Tag
The inverse of if: only execute
code if a certain condition is not met.
Description
unless is the inverse of if. It executes a block of code if a certain
condition is not met.
{% unless current_page.home? %}
{% include 'breadcrumbs' %}
{% endunless %}
You can also use elsif and else tags within an unless block,
though we find that using if
blocks are usually easier to understand in that case.
Parameters
None.
